Application January 24, 1956,. Serial No. 560,988 1 Claim. (Cl. 119-14.41)

.machines are employed, each carrying a pulsator possibly operating at a speed different from the speed of a pulsator on another machine. It is not practical to use the same machine on the same cow at each milking.

A primary object of the present invention is to provide adapter means for pails in order to accommodate the pails and even weighing cans or jars or in the. absence of having thermore the elimination of moving parts.

The pail covers are changed slightly to receive and hold the adapters but otherwise the pails remain the same as when provided for individual pulsators.

will be better understood by those the following description of the invention as illustrated in the accompanying drawings, in which Fig. 1 is a view in side elevation of a structure as applied to both short tube and long tube milkers;

Fig. 2 is a view in top plan and partial section of the short tube milker pail cover;

Pig. 3 is a view of the pail cover in side elevation;

Fig. 4 is a View in vertical, central section on the line 44 in Fig. 2;

Fig. 5 is a view in transverse in 3; and

Fig. 6 is a View in Fig. 2.

Referring to Fig. 1, there is supplied a constant vacuum pressure line 15, to which is connected a pulsator 16 of that type well known to those versed in the art which will automatically operate under the constant vacuum pressure set up in the line to deliver a pulsating vacuum pressure in a line section on the line 55 in vertical section on the line 66 milking period. At each stall or there is provided a stall cock 19, all in the usual manner.

The invention will be described first in relation to its use with a short tube milker.

The pail is provided with a handle to receive thereunder the surcingle (not shown) as has just been mentioned. That structure is well known and is commonly employed. However there is a slight difference over the standard structure in the pail cover 22.

For convenience, in carrying the pail with the cover, the cover 22 is supplied with a handle 24. A well 26 is formed in the top of the cover 22 in a cylindrical vform, and is eccentric of the cover 22. That is, the well 26 is located to one side of the center of the cover 22 as is indicated in Fig. 4 particularly.

A boss 27 extends concentrically of the Well 26 and upwardly from the floor 28, terminating by a top face 29 slightly above the top'portion 30 of the cover 22. The externa diameter of this boss 27 is made to be such that flexible gasket 31 therein.

The boss 27 is provided with a frusto-conical bore 32 therethrough.

A check valve is provided to seat around the margin of the upper end of this bore 32 at the floor 29. As indicated in Fig. 4, a satisfactory form of this check valve generally designated by the numeral 33, embodies. a substantially semi-spherical valve head 34 which will seat around the margin of the bore 32 as indicated, and from the valve head 34 there is a body 35 suspended in the na ture of a weight normally tending to seatthe head34, even though the cover 22 may be tilted somewhat from the horizontal.

The adapter proper, generally designated by the numeral 36,

side of the adapter 36.

A second tube 42 is fixed to the side of the adapter 36, and

are fitted over the rigid metal ried by the adapter 36. A flexible tube 54 is engaged by ,in the adapter is the check valve one end over the end of the stall cock 55 connected to the constant vacuum line 15, and by its other end to the rigid metal tube 41 extending from the adapter 36. A second flexible tube 56 connects by one end with the pulsated vacuum line stall cock 19, and by its other end over the rigid metal tube 42 carried by the adapter 36.

With the milking machine thus set up, the two cocks 19 and 55 are opened, and the teat cups 21 applied to the cows teats in the usual manner. The teat cups 21 are of the usual type carrying flexible inflations Within a rigid 'metal shell (not illustrated in detail because of these elements being standard construction and well known in the art) so that the pulsating pressure from the line 18 is transmitted through the tube 56 to the upper chamber 38 of the adapter 36, and in turn this pulsating vacuum pressure is applied to the teat cups 21 through the smaller tubes 53; The tube 54 being connected to the nonpulsating line 15 which is maintained at a constant vacuum pressure communicates that vacuum pressure tothe lower chamber 39 of the adapter 36, lifting the check valve 33 and thereby vacuumizing the pail 20. The cover 22 is maintained on the pail 20 in the usual manner by a gasket, not shown. Thus, milk drawn from the cow drains through the tubes 23 and through the cover rigid tubes 49-52 to flow into the pail 20. The only shiftable part When the milking operation is completed, the stall cocks 19 and 55 are shut off, and the tubes 54 and 56 may be disconnected or left in position for attachment to the next milking unit to be used on the next cow brought into the stall. The pail 20 with its cover 22 may be taken to the milk room for unloading and then be brought back for a subsequent cow to be milked.

Therefore, it is to be seen that I have produced an exceedingly simple structure for the purposes intended, and since structural changes may conceivably be made in the structure as described, all without departing from the spirit of the invention, I do not desire to be limited to the precise forms shown and described beyond the limitations which may be imposed by the following claim.

I claim:

In a milking system employing a milk receiving vessel normally supported from a cow during milking, fixedwall teat cups with internal inflations, a constant pressure vacuum line, a pulsated vacuum line, and a pulsator located remotely from said vessel; the combination of a milk vessel cover; a milk receiving nipple fixed to said cover for each of said cups; a cylindrical boss fixed to and extending from said cover and having a frusto-conical bore entering from the underside and opening through the boss top side; a valve seat defined at said bore opening; a valve having a spherical underside resting on and sealing off said valve seat; and integral weight of less diameter than that of said bore hanging from the weight rocking the valve and maintaining it on its seat under tilting of the cover from the horizontal; an adapter cylindrical in shape open from both ends, one end telescoping with said boss; an internal transverse partition across said adapter dividing the adapter into lower and upper chambers; a constant vacuum line connector nipple carried by said adapter and opening into said lower chamber; a pulsated vacuum line connector nipple carried by said adapter and opening into said upper chamber; a nipple opening into said upper chamber for eachof sai-d teat cups to apply said pulsating 0 pressure thereto through the upper chamber; a quick detachable cap sealably engaging said adapter across its upper end; and a cover carrying member carried by and spaced above the cover and extending toward said adapter; said cover carrying member bearing against said adapter cap; and said adapter teat cup connector nipples being normally directed generally toward said cover carrying member.
